10C (1984AJ01)(See Energy Level Diagrams for 10C) GENERAL: (See also (1979AJ01).) and Table 10.19 [Table of Energy Levels] (in PDF or PS) here. Model calculations: (1981DE2G, 1982SA1U). Electromagnetic transitions: (1982RI04). Astrophysical questions: (1979MO04, 1979RA1C). Complex reactions involving 10C: (1979BO22, 1981MO20). Reactions involving pions (See also reactions 2 and 6.): (1979AL1J, 1979LI1D, 1980LE02, 1981AU1C, 1982COZV, 1982RO04). Other topics: (1979NOZZ, 1980NO1A, 1982DE1N, 1982NG01). Mass of 10C: Based on Q0 for 10B(p, n)10C and 12C(p, t)10C and the Wapstra masses for n, t and 10B, the atomic mass excess of 10C is 15698.8 ± 0.5 keV.
10C decays with a half-life of 19.255 ± 0.053 sec to 10B*(0.7, 1.7): the branching ratios are (98.53 ± 0.02)% and (1.465 ± 0.014)%, respectively (1972RO03): see reaction 41 in 10B.
Angular distributions of π- groups have been measured at Ep = 185 MeV (1973DA09; to 10C*(0, 3.36, 5.28, 6.63)), at Ep = 200 MeV (1980SJ02; 10Cg.s.) and at Ep = 800 MeV (1979HO13; to 10C*(0, 3.35, 5.3, 6.6)). Ay measurements have been reported at Ep = 200 MeV (1980SJ02; 10Cg.s.) and 200, 225 and 250 MeV (1982LO02; 10C*(0, 3.35, 5.28, 6.6)). See also (1979AJ01, 1979JO1C, 1979ME2A, 1981AU1C, 1981BO1D, 1982HO1C, 1982NA1K).
See (1982RO04).
The Ex of 10C*(3.35) = 3352.7 ± 1.5 keV, τm = 155 ± 25 fsec, Γγ = 4.25 ± 0.69 meV. Angular distributions have been measured for n0 and n1 groups and for the neutrons to 10C*(5.2 ± 0.3) at Ep = 30 and 50 MeV: see (1974AJ01, 1979AJ01).
Angular distributions have been measured at E(3He) = 14 MeV and 217 MeV: see (1979AJ01). The latter [to 10C*(0, 3.35, 5.6)] have been compared with microscopic calculations using a central + tensor interaction [Jπ = 0+, 2+, 2+] (1976WI05). Structures have been reported at Ex = 5.22 ± 0.04 [Γ = 225 ± 45 keV], 5.38 ± 0.07 [300 ± 60 keV] and 6.580 ± 0.020 MeV [190 ± 35 keV] (1975SC27). [It is not clear which of the 5.2 - 5.4 MeV states is the 2+ state studied by (1976WI05).]
See (1982DO01).
Angular distributions have been reported at Ep = 30.0 to 54.1 MeV [see (1974AJ01, 1979AJ01)] and at Ep = 80 MeV (1979SH09; t to 10C*(0, 3.35, 5.28). L = 0, 2 and 2 thus leading to 0+, 2+ and 2+ for these states [but note that the "5.28 MeV" states is certainly unresolved]: see reaction 5 and Table 10.19 (in PDF or PS). 10C*(6.6) is also populated. The excitation energy of 10C*(3.4) is 3353.3 ± 1.0 keV (1974BE66), 3354.1 ± 1.1 keV (1978RO08) [based on Qm]. See also (1979NOZZ, 1980NO1A) and (1982BE1Z; theor.).
At E(3He) = 70.3 MeV the angular distributions of the 6He ions corresponding to the population of 10C*(0, 3.35) have been measured. The group to 10C*(3.35) is much more intense than the ground-state group: multi-step processes may be important (1973KA16). (1976DE27) suggest, on the basis of an FRDWBA analysis, that the process can be interpreted as a direct-cluster transfer to both final states.
